Sudipta Kundu

I am a Marie Skłodowska-Curie Postdoctoral Fellow in the Department of Physics, working with Prof. Marina Filip. I obtained my PhD from the Indian Institute of Science, Bangalore, and subsequently held postdoctoral positions at Stanford University and the University of Cambridge.

My research explores the electronic, optical and vibrational properties of materials using first-principles calculations and many-body theory. I am particularly interested in how interactions between electrons, excitons and lattice vibrations shape excited-state behaviour. My work spans low-dimensional semiconductors, van der Waals heterostructures, halide perovskites and molecular crystals, addressing phenomena such as exciton confinement, electron–phonon coupling and exciton–polaron formation.

At Oxford, I aim to understand how structural complexity and lattice dynamics influence excitonic properties, localization and energy
transport. I am also interested in combining first-principles methods with machine learning to investigate anharmonic vibrations and
finite-temperature dynamics. The broader goal of my research is to connect microscopic mechanisms with experimentally measurable properties and identify ways to control material behaviour for optoelectronic and energy applications.
